Patent GB-1405236-A (GB)
Title: Apparatus for controlling the flight of a vertical or short take- off and landing craft
IPC: B64C27/57
Filed: 1973-02-20
Abstract: 1405236 Aircraft instruments SPERRY RAND CORP 20 Feb 1973 [28 Feb 1972] 8180/73 Heading B7W An instrument 17 particularly for facilitating the final stages of landing a helicopter comprises roll and pitch indicator bars 18 and 19, and altitude pointer 21 actuated respectively by driving units 22a, 22b and 22c. The apparatus is intended to enable the aircraft to avoid speed/ altitude conditions which are unsuitable for a given helicopter and to control it after capturing a glide slope beam from about 800 feet down to 100 ft, assumed to be the breakout point from existing cloud cover, after which the pilot may land or hover with the aid of visual cues. The roll control channel comprises computer 23 and a mode selector 24 which receives inputs from a VOR/LOC receiver 26, heading select error unit 27, course select error unit 28 and a roll pick-off of a vertical gyro 29. The altitude control channel 31 includes a mode selector 32, containing switches S1, S2, S3. Before capturing the glide slope beam switches S1 and S2 are in the positions shown in the drawing so that a signal from a barometric altitude hold unit 33 is delivered to driver 22c whereby any deviation from the reference altitude will be observed by the pilot so that he may correct by actuating the collective pitch stick. For descent along the glide slope beam switches S1 and S2 are moved down as viewed in the drawing thereby disconnecting unit 33 and connecting a glide slope receiver 38. In the event of a baulked landing the pilot would move switches S2 and S3 to their upper position to disconnect the glide slope unit 38 and to apply a fixed bias go-around signal to driver 22c. The longitudinal control channel 37 contains a pilot operated unit 49 for selecting desired aircraft velocity during cruise flight prior to locking on to a glide slope beam and a programmed variable reference velocity unit 51 is set during that regime so that its signal is greater than that selected by the pilot. A least-value select unit 52 passes the signal applied thereto from unit 49 and blocks the signal from unit 51, the output signal passing through a mode selector 54 to a summing amplifier 56 where it is subtractively combined with the output from an actual-airspeed sensor 57 for transmission to driver 22b. A pitch attitude signal from vertical gyro 29 is fed in at 67 so that when the airspeed has been correctly adjusted the pitch indicator bar 19 is restored to its centre position. Reference velocity unit 51 is employed also in apparatus which ensure either a constant or variable deceleration of the helicopter from its cruise mode to the breakout point.
